Are mushrooms vegetarian?

When it comes to vegetarianism, there are often debates about what foods can be considered truly vegetarian. One such food that sparks controversy is mushrooms. While mushrooms are widely consumed by vegetarians, there is some confusion about whether they can be classified as vegetarian. In this article, we will delve into the topic and explore the reasons behind the debate.

The definition of vegetarianism

Before we can determine whether mushrooms are vegetarian, it is important to understand the definition of vegetarianism. Vegetarianism is a dietary practice that excludes the consumption of meat, poultry, and seafood. However, there are different types of vegetarians, including lacto-vegetarians, ovo-vegetarians, and vegans, who have additional restrictions on dairy products and eggs.

Mushrooms: A plant or an animal?

The confusion surrounding the vegetarian status of mushrooms arises from their classification. While mushrooms are often grouped with vegetables, they are not technically plants. Mushrooms belong to the fungi kingdom, which is a separate biological classification from plants and animals. Fungi are heterotrophic organisms that obtain nutrients by decomposing organic matter.

Why mushrooms are considered vegetarian

Despite not being plants, mushrooms are generally considered vegetarian for several reasons:

  • Nutritional profile: Mushrooms are rich in essential nutrients such as vitamins, minerals, and fiber. They can be a valuable addition to a vegetarian diet, providing important nutrients that are typically found in animal products.
  • Accepted by vegetarians: Mushrooms have been widely accepted as a vegetarian food by the vegetarian community for many years. They are commonly used as a meat substitute in vegetarian dishes due to their unique texture and umami flavor.
  • Alternative protein source: For vegetarians who are looking for plant-based protein sources, mushrooms can be an excellent option. They contain all the essential amino acids, making them a complete protein source.

Arguments against mushrooms being vegetarian

While mushrooms are generally considered vegetarian, there are some arguments against their classification:

  • Animal-like characteristics: Some argue that mushrooms should not be considered vegetarian because they share characteristics with animals. For example, mushrooms have chitin in their cell walls, which is also found in the exoskeletons of insects and crustaceans.
  • Non-plant origin: Since mushrooms do not belong to the plant kingdom, some argue that they should not be classified as vegetarian. They believe that vegetarianism should only include foods derived from plants.

The verdict

While the debate continues, the general consensus among vegetarians is that mushrooms can be considered vegetarian. The nutritional benefits and widespread acceptance of mushrooms in vegetarian diets outweigh the arguments against their classification. Ultimately, the decision to include mushrooms in a vegetarian diet is a personal choice.

It is important to note that individuals following a strict vegan diet may choose to avoid mushrooms due to their fungal nature. Vegans typically avoid all animal-derived products, including those that are not technically animals but share characteristics with them.


In conclusion, mushrooms are widely accepted as a vegetarian food due to their nutritional profile, acceptance by vegetarians, and their potential as an alternative protein source. While there are arguments against their classification, the majority of vegetarians include mushrooms in their diet. As with any dietary choice, it is important for individuals to make informed decisions based on their personal beliefs and preferences.
